Description
Technical field
The utility model relates to a kind of zinc device of smearing, and relates in particular to a kind of permanent magnetism and smears the zinc device.
Background technology
At steel, in the Industrial processes of iron coil galvanizing, after galvanized pipe comes out from the zinc pot, its surface is with the zinc liquid that surpasses thickness of coating, enterprise is general to adopt traditional airblade device to erase for unnecessary zinc liquid, its principle of work is to utilize high pressure gas that the unnecessary zinc liquid in surface is blown away, but this technology causes that easily surperficial plating layer is in uneven thickness, high pressure blow-gas also easily makes zinc liquid oxidation and atomizing, zinc liquid oxidation meeting causes the waste of metallic zinc, the atomizing of zinc liquid permeates in the air zinc liquid, polluted air causes environmental quality to seriously influence, and further harm humans is healthy.
The patent No. is that 200720035840.7 Chinese patent discloses a kind of steel-wire galvanizing and smears and wipe away device, be that electromagnetic generator is housed around the steel wire that goes out the zinc pot, electromagnetic generator comprises electromagnetic induction coil and current control device, the output of current control device links to each other with electromagnetic induction coil, electromagnetic induction coil is shape in the shape of a spiral, and galvanized steel wire passes from the electromagnetic induction coil center.Electromagnetic generator produces alternating magnetic field or pulsed magnetic field around steel wire, and at zinc laminar surface generation induced current, alternating magnetic field or pulsed magnetic field and induced current interact and produce long-range navigation magnetic force, make zinc laminar surface zinc liquid pressurized all around, and and the gravity acting in conjunction, impel zinc liquid to reflux, thereby reduce galvanized layer thickness.This device can not produce zinc liquid oxidation and atomizing, and it is effective to smear zinc; But the gravity acting in conjunction that long-range navigation magnetic force that this device produces and zinc liquid are subjected to self is in zinc liquid, and controllability and poor stability cause reliability not high.
The utility model content
The utility model is for solving the prior art problem, provides a kind of and smears that zinc is effective, the permanent magnetism of environmental protection is smeared the zinc device.
The technical solution of the utility model is: a kind of permanent magnetism is smeared the zinc device, comprise the zinc pond, it is characterized in that: the exit in described zinc pond is provided with permanent magnetic device, described permanent magnetic device comprises some permanent magnets, described permanent magnet distributes ringwise, surround the hole of passing through that is used for by steel pipe, and the magnetic line of force that produces of permanent magnet runs through and passes through the hole.
The magnetic line of force that permanent magnet produces runs through and passes through the hole, when remained on surface has the steel pipe of unnecessary zinc liquid to pass through permanent magnetic field, zinc liquid cutting magnetic line, according to the law of electromagnetic induction, produce eddy current in the zinc liquid, opposite according to the magnetic field that the Lenz's law eddy current produces with the variation of inducedmagnetic field, thus opposite electromagnetic force produced, utilize this electromagnetic force that the unnecessary metallic zinc liquid that floats on the zinc coat is removed from the surface of steel pipe; And zinc liquid is many more, and then electromagnetic force is bigger, and the zinc liquid of erasing is just many more, and zinc liquid is few more, and then electromagnetic force is less, and the zinc liquid of erasing is few, when the size of electromagnetic force and zinc liquid when the sticking power of steel tube surface balances each other, remaining zinc liquid can not erased.Plating layer is even after smearing zinc, avoids zinc liquid oxidation meeting to cause the waste of metallic zinc, avoids the atomizing of zinc liquid that zinc liquid is permeated in the air, and polluted air causes environmental quality to seriously influence; And because of magnetic line of force runs through whole galvanized pipe, smear the zinc effect and not only can realize, also can realize that it is identical that the zinc effect is smeared on inside and outside surface at the internal surface of pipe at the outside surface of pipe.
As preferably, described permanent magnet is along annular uniform distribution.The permanent magnet uniform distribution makes magnetic line of force be evenly distributed, and it is identical to act on galvanized pipe magnetic force everywhere, and it is identical that galvanized pipe is smeared the zinc effect everywhere, and plating layer thickness everywhere is identical.
As preferably, the N utmost point and the S utmost point of adjacent permanent magnet are arranged in the same way.
As preferably, the N utmost point and the S utmost point of adjacent permanent magnet are staggered.
The different arrangement modes of permanent magnet can produce different magnetic line of force and arrange, and produce the different effects of erasing.
As preferably, described permanent magnetism is smeared the zinc device and is also comprised e Foerderanlage, and described e Foerderanlage is provided with the anchor clamps that insulating material is made.
As preferably, the transfer rate of described e Foerderanlage is 2～5 meter per seconds.By adjusting the speed of carrying, can regulate the thickness of zinc liquid plating layer.
As preferably, described permanent magnetic device also is provided with setting device.
As preferably, described setting device is a calutron.The setting of calutron can be regulated the size by magnetic force in the hole within the specific limits, reaching the purpose of regulating the power size of erasing, can this regulate the thickness of smearing entrapped zinc layer behind the zinc; And this calutron only is used for the magnetic force size adjustment in the certain limit, and energy consumption is extremely low.
As preferably, described setting device is the permanent magnet position control.The permanent magnet position control is regulated the power in magnetic field by the radial position of regulating permanent magnet.
In sum, the utlity model has following advantage:
1, do not need to adopt electromagnetism, greatly save production cost;
2, magnetic force adjustable size, magnetic force direction is adjustable, and it is adjustable to smear the zinc effect, and it is effective to erase;
3, the inner and outer wall of pipe all can realize smearing zinc, and it is convenient to smear zinc, and technology is simple;
4, the transfer rate of tubing is adjustable, and the thickness of plating layer is adjustable;
5, zinc liquid oxidation, atomizating phenomenon can not occur, and the technology cost is low, does not pollute the environment.
